Temperature Distribution and Heat Exchange in Multipass Shell-and-Tube Exchangers with Baffles

Abstract

A model predicting the temperature distribution and the mean temperature difference in multipass shell-and-tube heat exchangers with baffles is presented. The exchanger is treated as a cascade of cells with mixing taking place in each fluid. From the computed results, design rules are deduced to enable the choice of the construction that leads to the highest efficiency. The effect of leakage currents on exchanger effectiveness is ignored in this analysis and is treated separately in another paper.
